I don't think there is a difference between the rear valances.

 

huh... they show two part numbers in the NPD book....

 

Yes there is a big difference in the two valances. The difference is were the valance attaches to the rear bumper under the liscense plate. I would guess that the differences between the 70 bumper and the 71,72 bumper in this area is what makes the attachment point different. Otherwise the rest of the valance is the same. Long ago I tried to install a 71,72 valance on a 70 bumper and the holes that attach the valance to the center of the bumper were not even close. If you look at the two valances next to each other it is plain to see that the two parts are different.

 

:yes: I didn't know this until it was too late and now have a nice painted valence up in my rafters that I can't use.

 

Well, I learned something new today,that I'll make a note of. Thanks fellas

 

Thanks Guys! I picked it up yesterday and put it up on the shelf with my 71 rear bumper to be installed at some point in the next decade...
